3 and 4, the cartridge fastening part 100 includes a fastening part housing 110, a first shaft 120, a guide part 130, a first magnet 131 and a stationary magnet 132. can be configured.

The fastening part housing 110 is a base on which the cartridge 200 can be fixed to the hand piece 10. The fastening part housing 110 is provided with a space on the inside, and one side may be fixed to the handpiece 10 and installed. A space in which the guide part 130 to be described later can be moved by the driving rod 12 may be provided inside the fastening part housing 110 . The fastening part housing 110 may be configured in a rectangular parallelepiped shape having a rather elongated shape along the moving direction of the guide part 130 . A part of the fastening part housing 110 may be cut so that the driving rod 12 provided in the hand piece 10 can be inserted into the other side. As an example, an insertion hole is provided on the side of the fastening unit housing 110 to allow the driving rod 12 to be inserted.

The first shaft 120 may be provided extending along a long side within the fastening part housing 110 . The first shaft 120 may be provided at a point spaced a predetermined distance from the end of the fastening part housing 110, and both ends may be connected to and fixed to the inner surface of the fastening part housing 110, respectively. The cross section of the first shaft 120 may include a rotation preventing structure to prevent the rotation of the guide unit 130 moving on the first shaft 120 . For example, the first shaft 120 may have a rectangular cross section to prevent rotation of the guide unit 130 . However, although not shown, as another example, the anti-rotation structure may be configured in a shape corresponding to each other in the form of a guide unit 130 and a protrusion/groove.

The guide unit 130 is configured to guide the movement of the holder of the transducer 240 in the cartridge 200 using magnetic force. The guide unit 130 is configured to reciprocate in one direction on the first shaft 120 . A fixed magnet 132 and a second magnet 231 may be provided in the guide part 130 . The guide part 130 has a hole formed in a horizontal direction so that the first shaft 120 can be inserted therein, and may extend a predetermined length in a vertical direction based on the hole. Referring to FIG. 3 , a fixed magnet 132 is provided on the upper side of the guide part 130, and the pole is provided toward the side so that magnetic force can be concentrated in the lateral direction. The first magnet 131 is provided on the lower side of the guide part 130, and a pole may be provided in the lower direction so that magnetic force is concentrated toward the lower side.

As a result, when the position of the guide part 130 is adjusted within the cartridge fastening part 100, the position of the first magnet 131 is adjusted so that the position of the transducer holder 230 described later can be adjusted.

The cartridge 200 may include a cartridge housing 210, a second shaft 220, a transducer holder 230, a transducer 240, and a second magnet 231.

A space is formed inside the cartridge housing 210, and the second shaft 220, the transducer holder 230, and the transducer 240 can be accommodated as a base. The cartridge housing 210 may have a cross-sectional shape of a long rectangular shape in one direction. The cartridge housing may include an upper housing 211 and a lower housing 212 . The upper housing 211 may have a hollow formed in a central portion and include a separator 250 closing the hollow. The separation membrane 250 may have a thin thickness while preventing fluid flow. The separator is disposed between the first magnet 131 and the second magnet 231 when the cartridge is fastened to the cartridge coupling part. Therefore, by making the distance between the end of the first magnet 131 and the end of the second magnet 231 extremely small, it is possible to secure attraction by magnetic force.

Cartridge housing 210 may be provided with a close contact so that one side can be in close contact with the skin. The contact portion is configured to be flat, so that when it is in close contact with the skin, the curvature of the skin is minimized, so that the transmission of ultrasonic energy can be maintained at a constant level.

The second shaft 220 may be provided parallel to the long side of the cartridge housing 210 . The second shaft 220 may be disposed at an angle parallel to the first shaft 120 when the cartridge 200 is mounted in the cartridge coupling part 100 . The second shaft 220 may include a rotation prevention structure similar to the first shaft 120 . As a structure for preventing rotation of the second shaft 220, it may be configured in a shape having a square cross section.

One side of the transducer holder 230 is configured such that the transducer 240 can be fixed thereto and is configured to move along the extension direction of the shaft on the second shaft 220 . A hole may be formed in the transducer holder 230 through which the second shaft 220 may be inserted. The hole may have a rectangular shape corresponding to the shape of the cross section of the second shaft 220 . One side of the transducer holder 230 may extend a predetermined length toward the cartridge fastening unit 100 from the shaft connection position. A second magnet 231 may be provided at a portion extending upward with reference to FIG. 3 . The pole of the second magnet 231 may be disposed toward the upper side so that the magnetic force density may be increased in a direction toward the first magnet 131 of the cartridge coupling part 100 .

The transducer 240 may be configured to generate ultrasonic energy. The transducer 240 may be configured to focus ultrasound energy outside the contact portion of the cartridge housing 210, that is, within skin tissue when the contact portion is in close contact with the skin. Therefore, it is possible to generate deep heat inside the skin surface and treat the tissue. Meanwhile, the configuration of the transducer 240 may be a widely used configuration.

However, in the above example, an example in which one first magnet 131 and one second magnet 231 is provided is shown, but a plurality of magnets having polar directions opposite to each other are combined to form the first magnet 131 and the second magnet 131. Each of the magnets 231 may be configured. In this case, since the coupling between the first magnet 131 and the second magnet 231 can be more accurately performed, position errors in the horizontal direction can be minimized.

Meanwhile, a wire may be provided to supply energy to the transducer 240 . One side of the wire may be connected to the transducer 240 and the other side may be connected to a terminal on one side of the cartridge housing 210 . Terminals are provided through the cartridge housing 210 and may be configured to be electrically connected from the outside of the housing. The terminal may be electrically connected to one side of the cartridge fastening unit 100 or one side of the handpiece 10 when the cartridge 200 is mounted on the cartridge fastening unit 100 .

On the other hand, the cartridge housing 210 is configured to completely prevent the outflow of the liquid medium by sealing the area through which the terminal is installed. Therefore, even if the user grips or tilts the handpiece 10 in the reverse direction, the liquid medium in the cartridge 200 is prevented from leaking out.

Meanwhile, although not shown, a sensor unit is provided in the cartridge fastening unit 100 to determine the position of the guide unit 130 and/or the transducer holder 230 . As an example, the sensor unit may be provided as a position sensor to measure the position of the guide unit 130 and/or the transducer holder 230 . In addition, the sensor unit may be provided in the form of an encoder that measures the rotation angle of the motor, and may be configured to determine the position of the transducer 240 according to the driving amount of the motor. However, since this configuration of the sensor unit can be applied to a widely used configuration, further detailed description will be omitted.

5 is an operating state diagram for adjusting the horizontal position of the transducer 240.

Referring to FIG. 5 , the first magnet 131 and the second magnet 231 are coupled to each other so that their positions in the horizontal direction are synchronized in FIG. 5 and their positions are adjusted. At this time, the position of the guide unit 130 may be adjusted in a state in which the driving rod 12 inserted from the outside of the cartridge fastening unit 100 is in close contact with the stationary magnet 132 . The driving unit provided in the handpiece 10 is driven by a control input so that the length of the driving rod 12 inserted into the cartridge fastening unit 100 can be adjusted.

The position of the guide part 130 on the first shaft 120 may be passively adjusted by the driving rod 12 . At this time, as the guide unit 130 moves, the position of the second magnet 231 coupled to the first magnet 131 is adjusted by manpower, and finally the position of the transducer holder 230 is passively adjusted. can Meanwhile, as the driving rod 12 is inserted, the guide part 130 and the transducer holder 230 move to the left in FIG. 5 . Conversely, as the driving rod 12 escapes from the cartridge fastening part 100, the stationary magnet 132 in contact with the end of the driving rod 12 moves to the right in FIG. 5, and finally the transducer holder. The position of 230 is moved to the right.

When configured as described above, since the position of the transducer 240 can be moved by moving magnetic force in a non-contact manner, the treatment device 1 using focused ultrasound can be operated while perfectly maintaining the state in which the liquid medium in the cartridge 200 is accommodated. In addition, leakage of liquid can be prevented in advance even when the cartridge 200 is fastened and disassembled.

As described above, when the position of the transducer 240 is moved within the cartridge 200, the user can enlarge the treatment area without moving the position of the handpiece 10. That is, when the user adjusts the operation while the end of the cartridge 200 is in close contact with the skin, the position of the transducer 240 is finally moved within the cartridge 200 by the operation of the motor. At this time, as the position is adjusted, ultrasonic energy is transmitted so that a wide area can be treated. That is, when the transducer 240 is moved within the transducer 240, the frequency of movement of the handpiece 10, which is repeatedly performed to change the treatment position, can be reduced, so convenience of use can be maximized.

Hereinafter, an operation of initializing the position of the transducer holder 230 as the cartridge 200 is fastened to the cartridge coupling part 100 will be described with reference to FIGS. 6A to 6D.

6a, 6b, 6c and 6d are operational state diagrams illustrating an operation of initializing the position when the cartridge 200 is fastened.

Referring to FIG. 6A , the cartridges 200 are aligned and placed on the lower side of the cartridge fastening unit 100 .

Afterwards, referring to FIG. 6B , the cartridge 200 is mounted on the cartridge fastening unit 100 . At this time, the position of the guide part 130 and the cartridge 200 holder in the horizontal direction are somewhat spaced apart, so that movement by magnetic force does not occur.

Afterwards, referring to FIG. 6C , when the driving unit is driven by the control unit 20, the guide unit 130 is moved to the left end within the movable range by the driving rod 12.

Afterwards, referring to FIG. 6D , contrary to FIG. 6C , when the driving unit is driven by the control unit 20 , the guide unit 130 is moved to the right end within the movable range by the driving rod 12 .

6c and 6d, the guide unit 130 reciprocates a predetermined distance by driving the driving unit 11 and passes through the horizontal position where the transducer holder 230 is located. Therefore, by reciprocating the guide part 130 once at the maximum stroke distance, the first magnet 131 and the second magnet 231 are coupled and the positions of the guide part 130 and the transducer holder 230 are adjusted. can be synchronized.

However, the order described in FIGS. 6c and 6d is only an example and can be modified in any order for moving the guide unit 130 to the maximum stroke distance.

Meanwhile, when the positions of the guide part 130 and the transducer holder 230 are synchronized, the position of the transducer 240 can be finally adjusted by adjusting the position of the driving rod 12 as described in FIG. 5 . .

Therefore, when the cartridge is mounted on the cartridge fastening unit, it is possible to determine whether or not the cartridge is mounted by detecting an electrical signal. On the other hand, whether or not the cartridge is mounted can be applied in various ways other than the above-described method. As an example in which this step can be performed, a button is provided on one side of the cartridge coupling part or handpiece, and when the cartridge is mounted, pressing the button may generate an electrical signal.

The step of initializing the position of the transducer (S200) corresponds to a step of synchronizing the position of the transducer in the cartridge in a non-contact manner.

The step of adjusting the position of the transducer in a non-contact manner (S300) corresponds to the step of moving the magnet outside the cartridge to adjust the position of the transducer. When the position of the transducer is initialized, that is, when the position of the magnet outside the cartridge and the transducer are synchronized, the position of the transducer can be adjusted in a non-contact manner by adjusting the position of the magnet. In this case, the position of the transducer and/or the magnet measured by a separately provided sensor unit may be fed back to be used for position control.

The transducer control step (S400) corresponds to a step of controlling ultrasonic energy generated from the transducer. Ultrasonic energy generated from the transducer is configured to be focused outside the cartridge. Meanwhile, the transducer control step may further include a step of controlling the focal position of the transducer. In case of controlling the focal position of the transducer, the depth at which deep heat is generated can be adjusted, so that the treatment position can be adjusted in the depth direction. there will be In the step of controlling the focal length of the transducer, it is possible to adjust the position of the focal point where ultrasound is focused by adjusting the vertical position of the transducer.

Meanwhile, the step of controlling the transducer and the step of adjusting the position of the transducer in a non-contact manner are performed alternately or simultaneously, so that a wide area can be appropriately and uniformly treated.

On the other hand, as the skin treatment device using the focused ultrasound used in this control step, the skin treatment device using the focused ultrasound described with reference to FIGS. 1 to 6D may be used.

As described above, the skin treatment device using focused ultrasound and the control method according to the present invention have a simple configuration and can move the transducer while independently maintaining the environment in the cartridge, thereby ensuring operational stability.
